The water-retaining layer and the base are connected by a permeable coating. A drainage groove is provided on the upper surface of the water-retaining layer. The water-retaining layer and the elastic layer are connected by a drainage plate. The lower surface of the drainage plate has internal holes, and the upper surface of the drainage plate has permeable holes. A water guide groove is provided at one end of the drainage groove. This utility model enables the device to achieve a drainage function, facilitating timely drainage of water after rain and preventing rainwater accumulation that could cause the running track to become slippery and slip.
[0004] The existing equipment has the following problems when in use: after long-term use, the surface layer of the particles is prone to cracking, which reduces the overall structural stability of the runway. Furthermore, after being corroded by the environment, the base is prone to separating from the material, resulting in high maintenance costs in the later stages. Utility Model Content

[0010] In a further embodiment, the elastic layer is made of polyurethane, and the elastic layer and the connecting column are integrally molded.
[0011] In a further embodiment, the support is made of fiberglass and has several gaps inside. The gaps are filled with sound-absorbing panels, and the support works with the sound-absorbing panels to absorb motion sound and reduce noise transmission.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. By bonding the connecting post to the inside of the slot, the connection area between the elastic layer and the EPDM particle layer is increased, the connection stability is improved, the EPDM particle layer is prevented from breaking, and the service life of the PDM particle layer is increased.
